Bio
Chris Hardy is a Senior Systems Integration Engineer and the Principal Engineer for Cross Process Solutions. A 1994 graduate of Georgia Tech, he’s been with Cross for over thirty years and has worked on software design, migration, configuration, commissioning & start-up of multiple platforms across various process applications. Chris’s favorite types of applications are the unusual and the experimental. Where some engineers like every detail planned and known before startup, Chris loves working on things which will require dynamic commissioning – experimenting and changing things on the fly until the system works well. Outside of work, Chris enjoys spending time with his family, hiking, computer games, and astronomy.

A PID loop adjusts its OP to maintain its PV at its SP. Some PID loops cannot be satisfactorily tuned by adjusting the three primary constants. When combined with good basic tuning, advanced methods can improve stability, responsiveness, and limit overshooting.

The art of tuning a PID loop is to have it adjust its output (OP) to move the process variable (PV) as quickly as possible to the set point (responsive), minimize overshoot, and then hold the variable steady at the set point without excessive OP changes (stable).
